vela-environment

What problem does it solve?

This Skill helps users understand and effectively utilize environment variables within Vela pipelines, preventing common errors related to compile-time vs. runtime resolution and variable scoping.

Core Features & Use Cases

• Variable Scoping: Learn to set environment variables globally, at the step level, and understand their precedence.
• Substitution Syntax: Master ${VAR} for compile-time and $${VAR} for runtime variable expansion.
• Inter-Step Data: Pass dynamic data between pipeline steps using VELA_OUTPUTS and VELA_MASKED_OUTPUTS.
• Use Case: Dynamically set build targets or deploy environments based on branch names, or pass sensitive tokens securely between build steps.

Quick Start

Use the vela-environment skill to understand how to pass a build commit SHA as a Docker image tag.
